Re: Stacking two HPE 5130 EI switches using 10GBE?

Yes, it is possible !

The documents suggests the following:

When you select transceiver modules and cables, follow these restrictions and guidelines:
• Use Category 6A (or above) twisted-pair cables to connect 10-GE ports in a short distance.
• Use SFP+ or QSFP+ DAC cables to connect SFP+ or QSFP+ ports in a short distance.
• Use SFP+ or QSFP+ transceiver modules and fibers to connect SFP+ or QSFP+ ports in a long distance.
• The transceiver modules at the two ends of an IRF link must be the same type.
NOTE:
The transceiver modules and DAC cables available for the switch are subject to change over time. For the most up-to-date list of transceiver modules and DAC cables, contact your Hewlett Packard Enterprise sales representative.
